I need to install some smoke alarms on the property. Four interlinked ones to be exact.
I'm thinking of getting these ones (https://www.amazon.co.uk/SEBSON-Wireless-magnetic-interlinked-replaceable/dp/B07G3CYWRK/ref=sr_1_11?crid=MSQVKXIMY7W4&keywords=smoke%2Band%2Bheat%2Balarm%2Bmultipack&qid=1649110218&s=diy&sprefix=smoke%2Band%2Bhear%2Balarm%2Bmultipack%2Cdiy%2C56&sr=1-11&th=1)
In the description I notice "Radio frequency: 868MHz". Now I don't know if it's exactly 868, but it seems very close to the Z-Wave freq of 868.42Mhz. Any potential interference? Is there any cause for alarm? (no pun intended)
